Japan: Privately issued family relationship certificate, "Partnership certificate" for same-sex couples

General corporate judicial person Famiee (Location: Chiyoda-ku, Tokyo; Representative director: Yuki Uchiyama) shares the "Partnership Certificate" for the same-sex couple, the first family relationship certificate issued by the corporation in July 2020. We would like to inform you that a total of 17 companies, including the Mizuho Financial Group, have begun preparations for introduction for use when applying for welfare services within the company.

Outline of the project

"Famiee" is a project to promote the realization of a society in which diverse family forms are taken for granted.

  1. People of various family types, such as same-sex couples and factually married couples, who are not legally recognized as marital relationships can obtain a "family relationship certificate" that certifies family relationships regardless of the country or district in which they live. To be able to

  2. Increase the number of private companies that provide family services and rights based on family relation certificates

  3. Use blockchain technology to store semi-permanent data of family relationship certificates

Background of the project The concept of "family" has become very diverse in recent years. LGBT couples, married couples, parents and children who received sperms and eggs, parents and children with the help of surrogate mothers, etc. have a new family form that does not apply to the conventional concept of "married couple" "parent-child" "family" It is being visualized. However, in the social system created based on the conventional concept of family, those who live based on the new concept face many difficulties.

Challenges of introducing a partnership system

As one of the movements to solve the current situation of people with such diverse family types, Japan has already begun to introduce a partnership system for gay couples in multiple local governments. However, there are many challenges.

  • Only a resident of the municipality that issues the partnership certificate can obtain it (with some exceptions)

  • If you move from the municipality that issued the partnership certificate, the issued certificate will become invalid and you will need to apply again at the new location.

  • When applying, both parties must go to the public office together and the relationship may be open regardless of the intention of the parties

  • The introduction of the system requires strong leadership from the municipalities, and it takes time for the partnership system to be introduced to all municipalities in Japan.

  • Companies that provide services and benefits for same-sex couples often set their own rules to confirm the existence of a partner relationship because the requirements for issuing a partnership certificate differ for each administration.


■ Famiee's first family relationship certificate, "Partnership Certificate" for same-sex couples
Famiee will start issuing the "Partnership Certificate" for gay couples in July 2020 as the first family relationship certificate. Until this point, in October 2019, a private sector partnership certificate review committee was established to specialize in companies, parties, family law, etc. who participate in the purpose of the project. Together with lawyers, we discussed the issues and countermeasures and designed the service.

Responsibility for issuing certificates relating to family relationships requires that the validity of the certificate be secured semi-permanently and semi-permanently over the life of the human being, and that the parent, child, and the second or third generation have semi-permanent data stored.
For semi-permanent data storage, it is not a system managed by a private organization, it operates semi-permanently even without a central administrator, data tampering is impossible, and the system is highly robust (down Time zero) I think that public blockchain technology with security is necessary.
